Soladey-2 scientific trials
Canadian trial
A blind, two-way crossover clinical trial was carried
out by the College of Dentistry, University of Saskatchewan, Canada
with 80 high school children of both sexes aged 13-16 years. The aim of
the study was to compare the plaque removing ability of the Soladey toothbrush
with a toothbrush of identical appearance but with an imitation bar made of
synthetic resin (control brush) in place of the semiconductor. Both groups
were advised to use the brushes according to manufacturer's instructions for a
period of 3 weeks using a small amount of a standard toothpaste which was
provided.
The results of this study indicate that the Soladey toothbrush had better plaque removing ability on the buccal surfaces1
of all teeth than the control brush without the semiconductor.

Japanese trial
A study was carried out by the Department of Preventative and
Community Dentistry, Nippon Dental University at Tokyo and with 60 adult female subjects who were dental hygiene school
students. One group (32) used the Soladey and another group
(28) used a conventional toothbrush (control). The subjects' oral
conditions were examined 1, 2 and 3 weeks later using five standardised
tests.
After the 3rd week there was a significant improvement in
gingivitis2 and oral cleanliness in the group using the
Soladey compared with
the control group.
